Do we have a tool other than script(1) that can record I/O for a
command? FreeBSD's script(1), treats any left over args as a command
to run - which is just what I need. But netbsd's script has other
features which are cool too...
In adding the command foo to our script, I'm pondering the extra
subchild used - presumably to avoid using select? As it stands, this
introduces a race condition, in that:
script /tmp/x.log /bin/date
the command will exit and the child gets a SIGCHLD and finishes before
logging the output from the command. cvs log doesn't make mention of
introduction of this sub-child so perhaps it has always been there.
But ditching it and using select in the parent seems neater than
blocking unblocking signals to avoid the race?
